THEVENIN’S THEOREM
... • To measure Rth, with load resistance removed, also remove and replace source voltage by a short (jumper wire), then measure and calculate the Thevenin resistance zacross the Open Circuit terminals: • Rth is measured 6 Ohms. • Considering the jumper wire, 6 and 3 Ohms resistors are in parallel, and ...

G482 Mod 2 2.2.3 and 2.2.4 Resistance and Resistivity
... The filament RESISTANCE INCREASES with increasing pd (V). This is because as the pd (V) across the filament increases, its temperature increases and this makes the metal atoms vibrate with greater amplitude, causing a greater opposition to the flow of electrons (i.e. current). The Filament resistanc ...

Lumped element model
The lumped element model (also called lumped parameter model, or lumped component model) simplifies the description of the behaviour of spatially distributed physical systems into a topology consisting of discrete entities that approximate the behaviour of the distributed system under certain assumptions. It is useful in electrical systems (including electronics), mechanical multibody systems, heat transfer, acoustics, etc.Mathematically speaking, the simplification reduces the state space of the system to a finite dimension, and the partial differential equations (PDEs) of the continuous (infinite-dimensional) time and space model of the physical system into ordinary differential equations (ODEs) with a finite number of parameters.
